Commentary: PostgreSQL is standard for a wide range of causes, however what has the PostgreSQL neighborhood executed to make sure this lengthy march to reputation?
PostgreSQL went years with out getting a lot in the best way of accolades, simply steadily releasing predictable, secure code. These days, its reputation has boomed, prompting me to put in writing repeatedly about its success: Amazon simply open sourced a better path to PostgreSQL, Builders more and more pair MongoDB with PostgreSQL, survey finds, and Why Oracle’s missteps have led to PostgreSQL’s ‘second’ within the database market. I believed I used to be executed, after which System Initiative cofounder Adam Jacob started riffing on the reasons behind PostgreSQL’s success, inflicting me to marvel what makes the neighborhood behind PostgreSQL’s rise so totally different.
In spite of everything, as Jacob pointed out, “Different databases supply higher fashions for a given area of interest, however nothing so elegantly might be twisted into no matter form you want it to be.” Which may be true, however why is it true? Arguably most databases try to be malleable to a big selection of use circumstances. Even issues like time sequence databases that when appeared area of interest have gone common goal. So what did the PostgreSQL neighborhood get proper to permit it to not merely aspire to suit a variety of use circumstances, however truly ship?

Higher by design
There’s loads to like about PostgreSQL, together with its flexibility. After many years of being put to work, it is maybe not shocking that PostgreSQL might be simply tailored, as Jacob called out: “If you’d like, you’ll be able to simply make the database really feel fully customized to your area model–the utility might be fully summary from the underlying implementation. In fact, when you don’t love that, you’ll be able to be happy to simply construct migrations of the essential schema, and put that SQL instantly in your utility. Each paths work, each are optimized and understood.”
Once more, all nice, however PostgreSQL shouldn’t be distinctive in striving for this aim. Somewhat, it is considerably distinctive in truly attaining it.
For this, quite a lot of credit score goes to the one that first created the database: Michael Stonebreaker. As Berkeley pc science professor Joseph Hellerstein wrote about Stonebreaker’s legacy:
Whereas many issues have modified in 25 years, the essential structure of PostgreSQL stays fairly much like the college releases of Postgres within the early Nineties, and builders accustomed to the present PostgreSQL supply code would have little bother wandering by way of the Postgres3.1 supply code (c. 1991). All the pieces from supply code listing constructions to course of constructions to information constructions stay remarkably comparable. The code from the Berkeley Postgres workforce had glorious bones.
Crunchydata’s Craig Kerstiens builds on this, arguing that “[A]s a database it took a counterintuitive method to most. It was by no means the ‘simple to make use of’ database, [to be honest] it nonetheless is not when in comparison with some others. But it surely targeted on correctness. It has since turn into [easier] to make use of, however that dedication for 20 years on correctness issues.” This concept is echoed by Datasette founder Simon Willison: “I actually respect how excessive the bar is for launched options. When a brand new characteristic turns into accessible in PostgreSQL I do know I can belief it immediately, as a result of I understand how excessive their requirements are.”
Although the “bones” have been initially sound, it has been this dedication to correctness and high quality over a protracted time frame that actually marks PostgreSQL. Different open supply database communities, together with MySQL, argued the CockroachDB of us, have not executed fairly in addition to PostgreSQL on this regard (“MySQL had grown organically over time in a considerably much less principled method than PostgreSQL”).
PostgreSQL usually is not the primary with cutting-edge features–that’s probably not its goal. Somewhat, the PostgreSQL neighborhood has, over time, achieved one thing outstanding exactly by not aspiring to any outstanding, industry-changing performance: Boredom. Or, somewhat, as Google’s Kelsey Hightower adroitly expressed it, “Postgres is what occurs when tech will get so good, for therefore lengthy, it turns into boring.”
